  • The Zonit Z-PDS is the future of power distribution to the rack, offering the most space-saving and cost-effective power distribution solution on the market. It redefines how power is distributed in data centers, eliminating the need for additional Remote Power Panels (RPPs), cumbersome busway systems rack power strips and significantly reducing the number of Power Distribution Units (PDUs) required. It brings complete three-phase, A-B power redundancy to the rack, offering superior performance at half the cost of traditional distribution methods, making it a versatile and future-proof solution.
  • System level DC power system all in one house.
  • The HindlePower DC Disconnect Switch is a simple solution for these common battery requirements:
    • Battery connection repair
    • Battery load testing
    • Battery replacement
    Unit can also be used as a DC load disconnect switch.
  • **The Pure Lead Plus (PLP) has been the replacement of the High Rate Max (MR) product line since April 1st, 2024. PLP models are direct replacements in form, fit and function for their MR equivalent while also offering better performance than the MR models. All PLP models have been rigorously evaluated and are float compatible with their MR equivalent, ensuring safe integration into any existing string of MR.
